' Divided and this application filed M This invention relates to improvements in Work locating and guiding devices, plication being a, division of a co-opending application Serial No. 735,863, filed Sept. 4:, 1924, in the names of the present inventors. As herein illustrated the invention is embodied in a jig of novel construction for use in a machine such as agroove-forming machine .to locate relatively to the operating and to guide past said instrumentality, a blank for a tool bag adapted for use on a bicycle.

In the manufacture ofvarious kinds of bags, suit cases and the like, a blank is cut from. a sheet of leather, leather-board or other material of such a shape that when the blank is bent or folded ,into the form of the finishedarticle and the abutting edges of the blank are secured together, as by stitching,

produced. To facilitate bending of folding of the blanks they are usuall side of the blank which is to constitute the inside surface of the finished article. i J

In making some kinds of bags or small cases of irregular'contour, the lines along which the grooves are to be out are not parallel toany edgeof the blank and in such cases difl'iculty is experienced in rapidly and accurately forming the grooves. f One feature of the present invention consists in a jig of novel construction for .use in cooperation with a gage member to guide past an operating instrumentality a piece of Work to be operated upon along at least one line not parallel to any edge of the work, the jig comprising a flat plate having an edge portion for engaging the gage member to determine the direction of the relative movement of the work and the operating instrumentality while the work is being operated upon along said line, and means for locating the work relatively to the jig with said line parallel to said edge portion of the jig.

The invention will be particularly described with reference to the accompanying drawings, in which Fig. 1.isa plan View of a jig constructed in accordance with the present invention;

Fig. 4 is a sectional view taken along the IVIV of Fig. 3; and I Fig. 5 is a plan view of a blank in which. grooves have been formed by the machine shown in Fig. 2.

Referring first to Figs. 1 and 2 of the drawings, the improved jig 1O therein'shown con; sists of a fiat plate made of sheet material, such as plywood, of a thickness substantially equal to the thickness'of a blank X which is to be operated upon. The blank X is shapedto form a tool bag adapted for use on a bicycle, the blank being of the irregular formindicated in Fig. l. The blank'is shown as it appears after having been grooved to facilitate the folding of the blank into final shape, the blank having been provided for this pur a, b and c, the grooves b not being parallel to any edge of the blank but beingformed along lines which bear a definite angularrelation to the edges of the blank. v

In order toreceive the blank X and position it in fixed relation to thejig while the blank is being operated upon, an opening 12 is formed in the jig, the opening being of an irregular size and shape, corresponding to the size andshape ing providing the angularly related edge faces 14, 16, 18, 20 for engaging correspond ing edge faces ofthe blank. The. outer edge portions22, 24 and 26 of the jig 10 are respectively parallel to lines along which grooves such as the grooves a, band 0 are to-be cut. The. jig isprovidedalso with recesses 28 which are located at different pointsaround the blank-receiving opening 12 for receiving the grooving cutters as-they later emerge from the blank after forming grooves therein. Q

In using the jig shown in Figs. 1 and 2, a, blank, suchas the blank X, is fitted within the blank-receiving opening 12 and the jig, together with the blank, is placed upon the and in Great Britain September 6, 1923.
